The mounting accessory mounts the device on an operator index finger in either of: a side-mounted mode in which the primary housing is between the index finger and a thumb; and a top-mounted mode, in which the primary housing is on a back of the index finger. The device includes an accessory trigger on the mounting accessory and a primary trigger supported on the outer surface. In the top-mounted mode, the accessory trigger is between the index finger and the thumb, for activation by the thumb. In the side-mounted mode, the primary trigger is disposed on the side of the index finger for activation by the thumb of the operator.

BACKGROUND

Finger-mounted data capture devices, also referred to as ring scanners, can be used to capture barcodes and the like, e.g. for transmission to a computing device carried by the operator. Wearing a ring scanner may, however, impede certain other activities the operator of the ring scanner is required to perform.

Additional examples disclosed herein are directed to a data capture device, comprising: a primary housing supporting a data capture assembly and having inner and outer surfaces joined by a perimeter wall; a mounting accessory coupled to the inner surface of the primary housing, the mounting accessory configured to mount the data capture device on an index finger of an operator in a side-mounted operational mode, wherein the primary housing is disposed on a side of the index finger between the index finger and a thumb of the operator; and a primary trigger supported on the outer surface of the primary housing such that in the side-mounted operational mode, the primary trigger is disposed on the side of the index finger for activation by the thumb of the operator.

FIG. 1 depicts a data capture device 100 (also referred to herein simply as the device 100) configured to be worn on a hand of an operator (not shown). In particular, the device 100 is configured to be worn on an index finger of the operator. The device 100 includes a primary housing 104 that contains a data capture assembly such as barcode scanner (e.g. an image-based barcode scanner including one or more image sensors).

The primary housing 104 includes an outer surface 108, referred to as “outer” because in use the outer surfaces 108 faces outwards, away from the index finger on which the device 100 is mounted. The primary housing 104 also includes an inner surface opposite the outer surface (the inner surface is not visible in FIG. 1 ), and a perimeter wall 112 joining the outer surface 108 and the inner surface. The perimeter wall 112 includes a scan window 116 disposed in a forward portion thereof. The above-mentioned data capture assembly is located within the primary housing 104 such that image sensors or other suitable data capture sensors have a field of view extending out through the scan window 116.

The device 100 also includes a mounting accessory 120 coupled to the inner surface of the primary housing 104. As will be discussed below in greater detail, the mounting accessory 120 may be removably coupled to the primary housing 104. The mounting accessory 120 is configured to mount the device 100 on the index finger of the operator.

The device 100 includes a primary trigger 124 and an accessory trigger 128, each of which is configured to be activated by the operator (e.g. via depression of the relevant trigger by the thumb of the operator) to initiate a scanning operation via the data capture assembly. The primary trigger 124 is disposed on the outer surface 108 of the primary housing, while the accessory trigger 128 is disposed on the mounting accessory 120. More specifically, the accessory trigger 128 is disposed on a wall 132 of the mounting accessory 120 that is at a substantially right angle relative to the outer surface 108. In other words, the primary trigger 124 and the accessory trigger 128 are at substantially right angles relative to each other. The orientation and placement of the triggers 124 and 128 enable operation of the device 100 in either of a top-mounted mode and a side-mounted mode.

Various trigger devices can be used to implement the primary trigger 124 and the accessory trigger 128. In the present example, the primary trigger 124 is an inductive sensor, while the accessory trigger 128 is a button trigger. In other examples, various other types of triggers can be employed for either or both of the triggers 124 and 128 (e.g. capacitive sensors, pressure sensors, temperature sensors, light sensors, and the like).

Turning to FIGS. 2A and 2B, the top-mounted operational mode is illustrated. In particular, the device 100 is mounted on a right index finger 200 of the operator. In the position shown in FIGS. 2A and 2B, the primary housing 104 is disposed on the back or top 202, of the index finger 200. The primary trigger 124 is therefore substantially inaccessible to a right thumb 204 of the operator, while the accessory trigger 128 is accessible to the thumb 204. Therefore, in the top-mounted operational mode, the accessory trigger 128 is disposed on a side 206 of the index finger 200, between the index finger 200 and the thumb 204, for activation by the thumb 204 to initiate a scanning operation. The side 206 is the side facing away from the other fingers of the right hand, towards the thumb 204.

As will be apparent to those skilled in the art, in some scenarios the top-mounted operational mode may be impractical. For example, when the operator is required to reach into narrow spaces, such as between boxes or other packages, the primary housing 104 may impede such reaching by increasing a height “H1” between the lowest and highest points of the device 100, measured in a plane extending through the top 202 and bottom 207 of the finger 200. In the top-mounted operational mode, therefore, the height H1 is the distance between a lower surface 205 of the mounting accessory 120 (specifically, the lower surface of the wall 132) abutted against the bottom side 207, and the outer surface 108 of the housing 104. Various other tasks may also be impeded by the primary housing 104 in the top-mounted operational mode, such as operating certain vehicles (e.g. forklifts with shielded or recessed throttle handles). The device 100 therefore also enables scanning in a side-mounted operational mode, shown in FIGS. 3A and 3B.

Turning to FIGS. 3A and 3B, the side-mounted operational mode of the device 100 is shown. In the side-mounted operational mode, the primary housing 104 is supported on the side 206 of the index finger 200, between the index finger 200 and the thumb 204. The primary trigger 124 is therefore positioned for activation by the thumb 204, while the accessory trigger 128 (not shown in FIGS. 3A and 3B) is underneath the index finger 200. In the side-mounted operational mode shown in FIGS. 3A and 3B, a height H2 between the lowest and highest points of the device 100 is smaller than the height H1 shown in FIGS. 2A and 2B. Specifically, in the side-mounted operational mode the height H2 is the distance between the wall 132 of the mounting accessory 120 and an opposing wall 300 (or strap, or other suitable structure, as will be discussed further below) of the mounting accessory 120. The height H2 is smaller than the height H1 because the primary housing 104 contributes less, or not at all, to the height H2. The operator can therefore more readily reach into narrow spaces while operating the device 100 in the side-mounted mode. In side mounted operational mode of the device 100, the primary housing 104 height allows for optimal operation of primary trigger 124 by effectively utilizing the space between thumb and index finger without negatively impacting operator comfort. The size of the primary housing 104, and the position of the primary trigger 124 in side-mounted operational mode of the device 100 permits access and reach to the trigger without inducing fatigue on muscles in the palm (lumbricals and thenar).

The provision of distinct triggers, in the form of the primary trigger 124 on the primary housing 104 itself, and the accessory trigger 128 on the mounting accessory, enables the above-mentioned dual-mode operation of the device 100. As will be discussed below, the device 100 also includes certain additional features to enable, for example, ambidextrous operation of the device 100.

Referring to FIGS. 4 and 5 , exploded views of the device 100 are shown, with the primary housing 104 separated from the mounting accessory 120. The primary housing 104, in the illustrated example, is removably coupled to the mounting accessory. As seen in FIG. 4 , the mounting accessory includes a mounting surface 400 that faces the inner surface of the primary housing 104. The mounting surface 400 includes an electrical interface 402 for communicating with the primary housing 104. In the present example, the electrical interface 402 includes a set of electrical contacts, such as pogo pins. The mounting surface 400 includes a latching mechanism, which in the present example includes a movable (e.g. spring-loaded) latch 404 and a static latch 408. The latching mechanism cooperates with corresponding structures on the inner surface of the primary housing 104 (discussed below in connection with FIG. 5 ) to removably couple the primary housing 104 to the mounting accessory 120. In addition, the mounting accessory 120 includes a strap 412 for attachment to an index finger of an operator (e.g. the index finger 200 shown in FIGS. 2 and 3 ).

FIG. 5 illustrates an inner surface 500 of the primary housing 104, as mentioned earlier. The inner surface 500 is configured to engage with the mounting surface 400 of the mounting accessory 120. In particular, the inner surface 500 includes a pair of hooks 504 and 508, each configured to engage with either of the movable latch 404 and the static latch 408. That is, the primary housing 104 can be coupled to the mounting accessory 120 in either of two orientations, enabling ambidextrous use of the device 100.

The inner surface 500 also includes an electrical interface 512, such as a set of electrical contacts, configured to engage with the contacts of the interface 402 of the mounting accessory 120 and thereby interconnect the mounting accessory 120 with the primary housing 104. For example, the interfaces 402 and 512 transmit trigger press indications to a controller in the primary housing 104 when the accessory trigger 128 is activated.

Turning to FIG. 6 , attachment of the primary housing 104 to the mounting accessory 120 is illustrated. In particular, the static latch 408 is place into one of the hooks 504 and 508 (the hook 508, in the present example) by moving the mounting accessory 120 in the direction 600. The mounting accessory 120 is then pressed upwards in the direction 604, towards the inner surface 500 of the primary housing 104, to engage the movable latch 404 with the other hook (the hook 504, in the present example). The movable latch 404 retracts upon contact with the hook 504, and then extends into the hook 504 to retain the mounting accessory 120 against the primary housing 104. To remove the mounting accessory 120 from the primary housing 104, the primary housing is pushed towards the static latch 408 to compress the movable latch 404 into the retracted position. Such movement disengages the hook 508 from the static latch 408, and permits the end of the primary housing near the hook 508 to be released from the mounting accessory 120. The hook 504 can then also be removed from the mounting accessory 120.

As will be apparent, the hooks 504 and 508 can each engage either of the latches 404 and 408, permitting the primary housing 104 to be connected to the mounting accessory 120 in either of two orientations. In the orientation shown in FIG. 6 , the device 100 is configured for right-handed use, as the accessory trigger 128 is arranged for placement between the right index finger and right thumb when the device 100 is top-mounted. The primary trigger 124 is arranged for placement atop the right index finger in when the device 100 is top-mounted, and for placement between the right index finger and the right thumb when the device is side-mounted. Further, as illustrated in FIG. 6 (and also visible in FIG. 1 ), the scan window 116 is substantially aligned with one end 608 of the mounting accessory 120, while an opposing end 612 of the primary housing extends beyond the opposing end 616 of the mounting accessory.

The removable coupling of the primary housing 104 with the mounting accessory 120 also enables the device 100 to employ a variety of mounting accessories. In some examples, the primary housing 104 can be coupled with a mounting accessory that does not include an accessory trigger. In other examples, a mounting accessory can be coupled to the primary housing 104 that includes a ruggedized trigger.

In further examples, the primary housing 104 can be coupled with a mounting accessory that includes two accessory triggers, one on either side of the mounting accessory. Such a mounting accessory, as will be understood by those skilled in the art, enables ambidextrous use of the device 100 without changing the orientation of the primary housing 104 relative to the mounting accessory 120. An example of a dual-trigger mounting accessory is illustrated in FIG. 7 .

FIG. 7 illustrates a data capture device 700 including the primary housing 104 connected to a mounting accessory 720 that includes two opposing walls 732 and 734, rather than a single wall 132 as shown earlier. The wall 732 supports a first accessory trigger 728, for right-handed use in the top-mounted operational mode, and the wall 734 supports a second accessory trigger 736, for left-handed use in the top-mounted operational mode.

Turning now to FIG. 8 , certain internal components of the device 100 are illustrated. The device 100, and in particular the primary housing 104, includes a controller 800, such as a central processing unit (CPU), interconnected with a non-transitory computer-readable storage medium, such as a memory 802. The memory 802 can include a suitable combination of volatile memory (e.g. Random Access Memory (RAM)) and non-volatile memory (e.g. read only memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash). The controller 800 and the memory 802 comprise one or more integrated circuits (ICs).

The primary housing 104 also contains a data capture assembly 804 connected with the controller 800. The data capture assembly 804 can include one or more cameras or other image sensors, and/or laser emitter(s) and sensor(s) for detecting reflections of emitted laser beams, or the like. The primary housing 104 also supports the primary trigger 124 and the interface 512, as noted earlier. The primary housing 104 can also include a communication interface 808, such as a wireless communication interface (e.g. Bluetooth or the like) for communicating with another computing device (not shown).

The mounting accessory 120 includes the interface 402 and the accessory trigger 128, and can also include a memory 812. The memory 812 may contain, for example, an accessory identifier retrievable by the controller 800. The controller 800 can be configured to detect, for example, when the primary housing 104 has been connected with the mounting accessory 120, and can retrieve the accessory identifier from the memory 812 responsive to such detection. The controller 800 can then be configured, e.g. based on a mapping of accessory identifiers to trigger functions stored in the memory 802, to enable or disable one or both of the triggers 124 and 128. For example, some mounting accessories may not permit operation of the device 100 in the side-mounted mode, and the controller 800 can therefore disable the primary trigger 124 when such mounting accessories are connected.

In other examples, the controller 800 can be configured to detect whether the device 100 is operating in the side-mounted mode or the top-mounted mode, and can enable or disable one of the triggers 124 and 128 accordingly. Detection may be performed by receiving input from an operator, e.g. voice input, activation of another button, a specific sequence of activations of the triggers 124 and 128, or the like. In other examples, detection may be performed automatically by the controller 800, for example by disabling the other of the triggers 124 and 128 when two or more consecutive actuations of one of the triggers 124 and 128 are detected (indicating that that trigger is currently in use and the other can be ignored).
